"We know it is so, May. None recognizes our obligations, both to the living and the dead, more acutely than I do. A very famous man of European reputation will be here to-morrow, and if you, too, desire a representative, you have only got to say so." "I desire no representative armed with material craft or knowledge of criminal procedure. I am my own representative, and I come armed with greater power than any you can command on earth, Sir Walter. I mean my Maker's response to my prayer. I must spend the night in that room, and cannot leave Chadlands until I have done so. I trust to no human expedient or precaution, for such things would actually disarm me; but my faith is in the God I have served to the best of my power from my youth up. I entertain not the least shadow of fear or doubt. To fear or doubt would be to fail. I rely absolutely on the Supreme Being who has permitted this unspeakable sorrow to fall upon us, and there is no living man less likely than myself to fall a victim to the unknown spirit hidden here and permitted to exercise such awful control over us. The time has come to challenge that spirit in the name of its Maker, and to cleanse your house once and for all of something which, potent for evil though it is allowed to be, must yield to the forces of the Most High, even in the feeble hand of His minister." The doctor spoke. "Is it possible, sir, that you attribute your son's death to anything but natural physical forces?" he asked. "Is it possible to do otherwise? How can you, of all men, ask? Science has spoken--or, rather, science has been struck dumb. No natural, physical force is responsible for his end. He died without any cause that you could discover. This is no new thing, however. History records that men have passed similarly under visitations beyond human power to explain. If the Lord could slay multitudes in a night at a breath, as we know from the pages of the Old Testament, then it is certain He can still end the life of any man at any moment, and send His messengers to do so. I believe in good and evil spirits as I believe in my Bible, and I know that, strong and terrible though they may be and gifted with capital powers against our flesh, yet the will of God is stronger than the strongest of them. These things, I say, have happened before. They are sent to try our faith. I do not mourn my son, save with the blind, natural pang of paternity, because I know that he has been withdrawn from this world for higher purposes in another; but the means of his going I demand to investigate, because they may signify much more than his death itself. One reason for his death may be this: that we are now called to understand what is hidden in the Grey Room. My son's death may have been necessary to that explanation. Human intervention may be demanded there. One of God's immortal souls, for reasons we cannot tell, may be chained in that room, waiting its liberation at human hands. We
